My FI has 5 other siblings, 2 older brothers and 3 younger sisters, none of which are in the actual wedding party. I have one brother whom i'm very close with. He's not keen on the idea of having him as a groomsman since they are not that close. I can't put him as an usher. Should I press the issue (I know I can get my way) or should I just appoint him as a "bridesman?" How would I get him down the isle?
